Media Mergers in Nested Markets
Journal of Economics &Management Strategy, EarlyView.ABSTRACT We analyze the effect of media mergers in a model that stresses, on the one hand, the fact that media are two‐sided platforms willing to attract advertisers and viewers and, on the other hand, that strong competitors have emerged to challenge traditional media on both sides.

A Communication Model for Adaptive Service Provisioning in Hybrid Wireless Networks [PDF]
arXiv, 2007 Mobile entities with wireless links are able to form a mobile ad-hoc network. Such an infrastructureless network does not have to be administrated. However, self-organizing principles have to be applied to deal with upcoming problems, e.g. information dissemination. These kinds of problems are not easy to tackle, requiring complex algorithms. Moreover,

Reformulating the Critique of Human Capital Theory
Journal of Economic Surveys, EarlyView.ABSTRACT Despite criticism, human capital theory (HCT) has remained central for six decades to the teaching and practice of economics. This paper reformulates the critique of HCT, focusing on two aspects that are typically relegated to the margin.

Emergency Response Communications and Associated Security Challenges [PDF]
arXiv, 2010 The natural or man-made disaster demands an efficient communication and coordination among first responders to save life and other community resources. Normally, the traditional communication infrastructures such as land line or cellular networks are damaged and don't provide adequate communication services to first responders for exchanging emergency ...

Market Potential, Road Accessibility, and Firm Births: Evidence From 20 Years of Road Investment
Journal of Regional Science, EarlyView.ABSTRACT This paper investigates the causal effects of road accessibility, measured by market potential, on firm births in Portuguese municipalities between 1991 and 2016, a period marked by significant road improvements. We address the endogeneity of market potential by employing instrumental variables within Poisson Pseudo‐maximum Likelihood ...

A study of distributed QoS adapter in large-scale wireless networks [PDF]
arXiv, 2012 Considering the comfortably establishing ad hoc networks, the use of this type of network is increasing day to day. On the other side, it is predicted that using multimedia applications will be more public in these network. As it is known, in contrary to best-effort flows, the transmission of multimedia flows in any network need support from QoS ...

The Surprisingly Robust Effects of Narratives in Supplier Negotiations
Journal of Supply Chain Management, EarlyView.ABSTRACT Narratives—or stories—are commonly viewed as powerful means to convince others, although it remains unclear how the narrator's use of deception in supplier negotiations influences their effectiveness. Grounded in narrative transportation theory, the authors investigated these dynamics using a vignette‐based experiment with 332 business‐to ...

Distributed Cross-layer Dynamic Route Selection in Wireless Multiuser Multihop Networks [PDF]
arXiv, 2014 In wireless ad-hoc networks, forwarding data through intermediate relays extends the coverage area and enhances the network throughput. We consider a general wireless multiuser multihop transmission, where each data flow is subject to a constraint on the end-to-end buffering delay and the associated packet drop rate as a quality of service (QoS ...

Neurogastroenterology &Motility, EarlyView.The novel manometric parameter Milan Score could be useful in predicting which patients with type 2 EGJ have a high likelihood of objective GERD, therefore discriminating which patients may need escalation of GERD investigation and management. ABSTRACT Introduction High‐resolution manometry (HRM) allows assessment of esophagogastric junction (EGJ ...

General Auction-Theoretic Strategies for Distributed Partner Selection in Cooperative Wireless Networks [PDF]
arXiv, 2010 It is unrealistic to assume that all nodes in an ad hoc wireless network would be willing to participate in cooperative communication, especially if their desired Quality-of- Service (QoS) is achievable via direct transmission. An incentivebased auction mechanism is presented to induce cooperative behavior in wireless networks with emphasis on users ...
